Bought Premium and now all my music is gone

[laylaimsmith]

I recently purchased Spotify Premium on a computer and when I logged into my account on my phone it doesn't register that I have a Premium account and asks me to sign up and pay again. I tried logging in with my username rather than my email and that seems to fix the Premium issue but when I log in that way all of the music I've saved is gone. Is there a way to have Premium and all of my previously saved information? I have so much music saved and I'd hate to lose it all just because I want to pay for the Premium service
